4 VERSATILE RAIL/ROAD EXCAVATOR 714MWRR AN EXCAVATOR FOR ALL COMPACTNESS With a tail radius of 1,565 mm, the 714 MWRR is able to work on a single track. Furthermore, thanks to its equipment kinematics it may be adapted to all site conditions, especially those with limited space available. PERFORMANCE Thanks to its kinematics, the equipment is efficient in all working positions. The lifting arm system with two asymmetric cylinders guarantees a homogenous lifting force both at low and high working heights. By railroad, travel speed is 22 km/h in both forward and reverse. The BUSCAN electronic system controls all vital components to optimise excavator operation and provide the operator with all data necessary for optimum machine use both on road or rail. As a professional working in a railway environment with limited space available, the 714MWRR meets all your needs with its remarquable com pactness and performances. 428 R =

5 RAILROAD WORKSITE APPLICATIONS 5 VERSATILITY= PROFITABILITY The 714 MWRR digs, loads, handles and may be equipped with a wide range of accessories. Using the standard quick-coupling system, the operator may switch from one accessory to another in seconds. The offset* feature considerably simplifies work as it allows both right and left bucket offset. *optional Compact boom geometry and a quick coupling system render the 714MWRR ideal for all applications on sites demanding an ever greater level of profitability.

6 VERSATILE RAIL/ROAD EXCAVATOR 714MWRR EASY TO OPERATE, INC Operation simplicity combined with a high level of safety and comfort increase the operator s efficiency and well-being during a long working day. Furthermore, the user-friendly controls and hydraulic functions render the 714 MWRR the ideal excavator or all applications. COMFORT A very spacious cab for a machine of this category: length. A panoramic view over the entire working zone, in particular thanks to the position of the lifting arm cylinders. Numerous storage spaces adapted to today s needs. The seat and arm rests may be adjusted independently to adapt the seating to the morphology of the user. A totally fold-away windscreen: the bottom section folds over the top section which is then folded under the roof. Ceiling skylight with sunscreen. Reduced noise in the cab thanks to improved noise insulation in the engine compartment. Stereo radio CD player. Double cab available as an option.

7 OMPARABLE COMFORT 7 VISIBILITY = SAFETY The 714 MWRR offers a panoramic view over the entire work zone thanks to the spacious cabin and position of lifting arm cylinders. The overall turret compactness provides clear visibility behind the machine. EASY AND INTELLIGENT OPERATION - Road functions identical to those of the 714MW. - Rail functions incorporated into the monitoring display and control keypad. HYDRAULIC TECHNOLOGIES ACTIVE CONTROL INSIDE LOAD SENSING: optimum equipment pressure suited to the effort requested, FLOW SHARING: pump output shared among all controls, simultaneous movement CYLINDER COUPLING: simultaneous control of boom cylinders and tandem drive with a single joystick or control the equipment in 3 stages without using the pedal. Switch the display from road to rail using the pull-down menu LCD screen Road functions LCD screen Rail functions Additional rail functions with keys F1 and F2

8 VERSATILE RAIL/ROAD EXCAVATOR 714MWRR A HIGH SAFETY LEVEL FOR RAILROAD APPLICATION The 714 MWRR meets SNCF approval criteria in France and is capable, after customization, of complying with regulations applicable in other EEC countries. Equipment height limitation on track with overhead wires isolated or not: - a two-position rod, connected to the boom cylinder, is used to select one of the two positions available. - a label in the drivers cabin indicates the setting procedure. Lift load limiter: - the machine s electronic system monitors the load lifted, turret position, and boom angle with sensors and warns against or prevents movement with could have an effect on the load position and thus guarantees machine stability. Angle sensor Turret rotation limitation to avoid hindrance of adjacent tracks: - rotation is limited to 18 left and right using a set of position sensors and a mechanical stop safety device (shaft). A staged speed control system slows the turret travel progressively to avoid excessive contact with the mechanical end stops. - if the machine is equipped with an offset facility, its position is monitored with sensors to avoid hindrance of adjacent tracks. Turret position sensor

9 VERSATILE RAIL/ROAD EXCAVATOR 714MWRR ADVANTAGES OF THE RAILROAD SYSTEM 9 The 714MWRR bogies are equipped with metal wheels with a diameter of 58mm which loading with raised wheels while still respecting railway regulations. The 714 MWRR is equipped with two bogies functioning independently. They are fastened directly to the front and rear ends of the chassis and replace the stabilizer and blade systems of the 714MW road model. EASY TO OPERATE The machine is driven with the same pedals as those used for road travel. The bogies are driven with a single high-torque hydraulic motor incorporated into the rear axle (transmission between wheels with a solid drive shaft) and supplied by the translation circuit of the 714MW road machine via a splitter unit fitted to the hydrostatic motor. As soon as the system has detected correct positioning of the machine on the rail (bogies lowered and turret aligned), the translation supply is switched over automatically. Option: second motor in the front axle provides improved adherence when changing the direction of travel EFFICIENT AND AUTOMATIC BRAKING Each bogie is equipped with a direct drum brake acting on both wheels of the same shaft. An automatic braking system when the accelerator pedal is released enables the machine to remain immobile during stoppage or work phases. Additional pressure on the brake pedal provides improved braking efficiency. The minimum front and rear passage angle of 3 makes it easier to enter and leave the railway track or to pass over obstacles (embankments for example).
